Its better you refer Release notes & Installation guide.
It seemed the easiet way for me to do this was to install the extensions EEAdmin.zip, EEPC.zip and EEGO and then install the packages MfeEEPC, MfEEAgent and EegoPackage in Evaluation mode.
I then created a Client Task and then a Client Task Assignment using Tags and then upgraded some machines.
It all went well:)
When I am happy that all is ok after a few days I will move from Evaluation into Current.
